CPT® Code 59320

The procedure described by CPT® Code 59320 refers to the cerclage of the cervix during pregnancy, a surgical intervention aimed at addressing an incompetent cervix. An incompetent cervix is a condition where the cervix begins to open prematurely, which can lead to complications such as miscarriage or preterm labor. This procedure is particularly indicated for women with a history of second-trimester miscarriages, those who have undergone cervical surgeries such as loop electrical excision procedures or cone biopsies, or those who have experienced other forms of cervical injury. The primary goal of cervical cerclage is to provide support to the cervix, preventing it from dilating too early and thereby reducing the risk of premature labor and delivery. Typically, this procedure is performed between 12 to 14 weeks of gestation; however, it can also be conducted as an emergency measure later in pregnancy if there are signs of cervical opening. The cerclage is placed using a vaginal approach, where the physician may employ techniques such as the McDonald-type cerclage, which involves weaving a purse-string suture around the cervix, or the Shirodkar-type procedure, which involves tunneling the suture subcutaneously around the cervix. Both methods aim to secure the cervix and maintain its closure throughout the pregnancy.
